Abstract: A pulsator device in which a second pulsator performs different movements according to rotating directions of a first pulsator so as to reduce water consumption and improve washing performance.

Abstract: A pulsator device that generates a composite stream of water to improve performance of a washing machine. The pulsator device includes a first pulsator configured to be rotated about a rotary shaft, a shaft connected to the first pulsator such that the shaft is rotated with the first pulsator, the shaft being eccentric with respect to the rotary shaft, and a second pulsator rotatably coupled to the shaft.

Abstract: Disclosed herein is a washing machine to generate rotating and vertical water streams simultaneously. The rotating water stream is generated by rotation of an outer pulsator, and the vertical water stream is generated by rotation of an inner pulsator. A rotating body is installed between the outer pulsator and the inner pulsator, to convert rotation into vertical movement. An inner wall of the outer pulsator is formed with a curved surface to come into close contact with the inner pulsator being moved vertically.

Abstract: In the washing machine, which has a tub installed in a main body, a spin basket rotatably installed in the tub, and a pulsator unit installed in the spin basket to generate a washing water current, the pulsator unit includes a first pulsator connected to a washing shaft of a driving device, a rod member installed on the upper surface of the first pulsator such that the rod member is tilted toward a central axis of the first pulsator at a designated angle, and a second pulsator coupled with the rod member such that the second pulsator is relatively rotated against the rod member.

Abstract: A washing machine capable of reducing the manufacturing cost of a circulation device installed to circulate water and capable of preventing water from being scattered when spraying circulating water into a spin basket is described. A tub cover of the washing machine includes a guide part provided with a connector, which is integrated with the tub cover, connected with a circulation passage, and inclined upward toward the tub cover, and an inclined surface inclined toward the spin basket at an inner edge of the tub cover, thereby reducing the manufacturing of the circulation device and preventing water from being scattered. The washing machine includes a circulation drain port formed at a side surface of a tub and a filtering duct connected with the circulation drain port, thereby reducing the manufacturing cost of the circulation device.

Abstract: Disclosed herein are a washing machine and a detergent supply path which guides detergent stored in a lower part of a main body of the washing machine to an upper part of the main body. The washing machine includes a main body; a support base removably mounted to the main body; a detergent storage unit mounted at a lower part of the main body to be moved in and out of the main body; a detergent supply path guiding the detergent stored in the detergent storage unit that is in the lower part of the main body, to an upper part of the main body; and a guide unit guiding movement of the detergent supply path according to the movement in and out of the detergent storage unit.

Abstract: Disclosed are a detergent dissolving device for a washing machine capable of improving solubility of detergent, and a washing machine having the same. The detergent dissolving device includes a powdered detergent box, and the powdered detergent box includes a detergent receiving portion, and a water feed portion defined at a periphery of the detergent receiving portion to feed water into the detergent receiving portion so as to cause rotating motion of water received in the detergent receiving portion. The detergent dissolving device further includes a cover provided to open or close the detergent receiving portion. The cover includes a water discharge portion to discharge the water out of the detergent receiving portion.

Abstract: Disclosed is a drum washing machine having a bubble generator to wash laundry using bubbles. The drum washing machine includes a tub to contain washing water; and a bubble generator generating bubbles and supplying the bubbles to the tub, the bubble generator including a bubble generation pump allowing the washing water to flow therethrough and an ejector unit formed integrally with one side thereof to mix air with the washing water. The drum washing machine minimizes a reduction of the speed of the washing water due to a passage resistance, and thus increases an amount of generated bubbles.
